Does hwupd work with Thinkpads?

Is windows tax really that bad? I mean I can get an OEM license for 12 dollars most of the time because of promotions. So if I as a consumer pay 12 dollars for an OEM version, I would expect Lenovo to pay much less. Also my first observation is that these laptops are far too big and powerful for my work with Linux. I work full time in Linux but I focus more on weight and form factor than CPU and GPU because all my wo…

Besides the windows tax aspect there is also the aspect of a vendor taking a bit of responsibility around what the user experience (hardware support etc) is like when running linux on their hardware. Offering an option for shipping with linux seems to serve as a catalyst for that.

I'd be a little surprised if that actually happens. Most likely they're shipping Linux for webdevs and people who want to avoid the Windows tax, neither of which they'll care much about supporting.

The word "factorial" makes no sense here. Maybe "fractional"? Besides, what is the fucking point of "scaling" at the display level? Isn't it exactly equivalent to setting the font size in points using your physical resolution?

No, it's not like setting font size. Actual fractional scaling as done by macOS and Wayland compositors is rendering at 2x and downscaling. e.g. 1.5 scale on a 3840x2160 display means you have 2560x1440 logical pixels (3840x(1/1.5) = 2560), applications render for 5120x2880 (2560x2=5120) and get downscaled for 3840x2160.

I mean, there's a substantial effort to developing the gaming platform on Linux. Maybe that's their audience?

From what I've seen that effort seems to be going into proprietary platforms like Stadia. There no guarantee that will trickle down to the open source community.

Valve has contributed a tremendous amount of open source work in order make Linux an even remotely viable gaming platform. I'm actually pretty impressed at how well they've done.

Ah, mon dieu! This is the first time I read about "logical pixels". It is horrifying.

>TB3 dock never works properly Do these even work on Windows?

My Lenovo 40AN workstation dock has worked very reliably under Windows.

Yeah, I just realized it's called fractional scaling too, my bad. It is still important though, because on 14inch desktops the Ubuntu interface looks way too small on 100% scale and way too big on 200%. At the end of the day you can think of fractional scaling as giving yourself more screen real-estate while at the same time keeping everything in a readable state.

I don't understand what you mean by the interface. Is it the font size? You can change it independently of everything else.

Most programs aren't coded to have all of their elements scale properly. You have icons, buttons, pictures, etc that may be bit mapped images, then you have other elements that are vector mapped. So if you just change the font size, you can read the text, but it may be in a text box that is too small (so it overflows).

So the best thing you can do, other than re-write all the applications that have been around for the last 30 years or more, is to make the app think it is writing to a display with a specific resolution. Then scale that up to whatever resolution your screen actually is. Then, any element that is bit mapped in the app may not look very crisp, but things like fonts or any element drawn by a UI library can be drawn at the screen's native resolution (because those libraries have been updated to know about the "fake" vs "real" resolution).

This is very similar to when you hit "ctrl +" in a modern web browser. If the web app says "place this element 25 pixels to the right", those are logical pixels and has little to do with actual screen pixels anymore.

Thinkpad A486 on Debian 10 here. Both ethernet chip and WiFi chip requires firmware so install is not straight forward. Wireless driver is marked as alpha and it shows ... weekly hard freeze on the menu. A shame as it could be a great laptop.
